Answer:

Gas

Explanation:

The properties of the three states of matter are:

solid : fixed shape, fixed volume, high density as the intermolecular forces are strong and the particles cannot move here there. Only vibrations are possible.

Liquid: Fixed volume but shape depends upon the container, density lower than solid but higher than air.

Gas: Not fixed volume and not fixed shape also. The density is least among the three states of matter. There are leas strong force of interactions between molecules. the thermal energy is highest among the three states of matter.

Thus answer is gas.

An acetylide anion is more stable than either a vinylic or alkyl anion due to Group of answer choices the greater stability of a
sashaice [31]

Answer:

the stabilization of the negative charge in orbitals with higher s character

Explanation:

Acetylide anion is a carbon anion compound or popularly called carbanion. Now Acetylide anion is sp hybridized. However acetylide anion tends to be more acidic as we move from sp³ to sp, hence acidicity increases, which makes sp to have the highest acidity and become the most  stable.

So, we can conclude that the acetylide anion is more acidic due to the stabilization of the negative charge in orbitals with higher s character and  as the s character increases, acidic nature of acetylide anion also increases.

Sodium carbonate reacts with silver nitrate according to the following balanced equation: Na2CO3 (s) + 2 AgNO3 (aq) → Ag2CO3 (s)
klemol [59]

Answer:

a) 2.01 g

Explanation:

  • Na₂CO₃ (s) + 2AgNO₃ (aq) → Ag₂CO₃ (s) + 2NaNO₃

First we <u>convert 0.0302 mol AgNO₃ to Na₂CO₃ moles</u>, in order to <em>calculate how many Na₂CO₃ moles reacted</em>:

  • 0.0302 mol AgNO₃ * \frac{1molNa_2CO_3}{2molAgNO_3}  = 0.0151 mol Na₂CO₃

So the remaining Na₂CO₃ moles are:

  • 0.0340 - 0.0151 = 0.0189 moles Na₂CO₃

Finally we <u>convert Na₂CO₃ moles into grams</u>, using its <em>molar mass</em>:

  • 0.0189 moles Na₂CO₃ * 106 g/mol = 2.003 g Na₂CO₃

The closest answer is option a).

A certain element exists as two different isotopes. 65.0% of its atoms have a mass of 24 amu and 35.0% of its atoms have a mass
Sauron [17]

Answer:

24.7 amu

Explanation:

An isotope is when an element can have different number of neutrons but they have same number of protons.

In order to calculate the average atomic mass with the given information do the following operations:

First change de percentages to fractional numbers, divide by 100.

I like to make a table, to organize all data and I believe is easier to understand.

65/100 = 0.65

35/100 = 0.35

% fraction

65.0 0.65

35.0 0.35

total100.0 1

Now multiply each mass with their corresponding fraction

24 (0.65) = 15.6

26 (0.35) = 9.1

%    fraction uma uma

65.0 0.65 24 15.6

35.0 0.35 26 9.1

total100.0    1          24.7

Finally you add the resulting mass and the units will be in uma.

15.6+9.1 = 24.7

Therefore the average atomic mass of this element will be 24.7 uma.
